Provided is an electrical coiled cable that has excellent durability, a small outer diameter, is light in weight, has low conductor resistance, and has excellent flexibility. A coiled cable (10) has a conductor coil (12) formed into a coil shape having a coil average diameter (D) by winding four conductor base lines (21-24) with a diameter (d) to each of which an insulating coating layer (42) is applied, the conductor coil (12) is set to have an spring index (D/d) represented by 2 ‰¤ D/d ‰¤ 4, and each of the conductor base lines (21-24) is configured by twisting a plurality of materials that have Æ0.008 to Æ0.05 and that are made of tough pitch copper, oxygen-free copper, or copper alloy wire.
